When the source code from Realtek was prepared for kernel inclusion,
some routines were refactored to reduce the level of indentation. This
patch repairs errors introduced in that process.

In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call
dev_alloc_skb(), which may fail and return NULL, but we do not check the
returned value against NULL before dereferencing the returned pointer.
This may lead to a NULL pointer dereference which means we'll crash - not
good.
In a separate call to dev_alloc_skb(), the debug level is changed so that
the failure message will always be logged.

An RX buffer is set to 9100 bytes to receive 8K AMSDU; however, an skb
of this size fails in the kernel.

If the radio enable switch is off when the driver is loaded, it is not
possible to get radio output until the driver is unloaded and reloaded
with the switch on.

create_workqueue is deprecated. The workqueue usage does not seem to
demand any special treatment, so do not set any flags either.

A previous conversion from semaphoreto mutexes missed the fact that one
of the semaphores was used in interrupt code. Fixed by changing to
a spinlock.

After merge of the rtl8192ce driver, a powerpc build fails with:
drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192c-sw.c: In function 'rtl92c_init_sw_vars':
drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192c-sw.c:76: error: implicit declaration of function 'vmalloc'
drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192c-sw.c:76: warning: cast to pointer from integer of different size

drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192c-sw.c:91: error: implicit declaration of function 'vfree'
The problem is fixed by explicitly including the appropriate header.

Allow drivers or rate control algorithms to specify BlockAck session
timeout when initiating an ADDBA transaction. This is useful in cases
where maintaining persistent BA sessions does not incur any overhead.
The current timeout value of 5000 TUs is retained for all non ath9k/ath9k_htc
drivers.
